1. Protect your body and clothes
2. Prevent Contamination spread (leave all lab coats outside of chemical free zones)
3. Fitting the Environment

Question 3

Types of Temperature-tolerant Gloves

Answer 3

Good with Extreme Temp and Corrosives - Zetex
Aluminum covered gloves good with extreme temp - Kevlar

Question 4

Types of Chemical-tolerant gloves

Answer 4

*Resists nitritc, sulfuric, and flouric acids, gasses, fumes, and don’t deform in cold temperatures - Butyl
* Liquid and aq solutions, weak acids and bases, salts, and ketones, but can react with allergies - Latex
* Organic solvents, oils, and organic acids and bases, elastic and durable - Neoprene
* Chlorinated compounds, good for fine work, resistant, durable and elastic - Nitirl
* Very Little protection - Vinyl

Question 5

What does the MEL vs TLV of Masks mean?

Answer 5

MEL - “Maximum Exposure Limit” before the mask begins to leak
TLV - “Threshold Level” maximum concentration allowed in the atmosphere to allow for safety

Question 6

Respirator Classifications

Answer 6

N - not resistant to oil
R - resistant to oil
P - oil proof (high efficiency particulate air filter)
BFE - bacterial filtration efficiency
VFE - viral filtration efficiency

Question 7

Gas Mask Colors (at least 5)

Answer 7

*White = Acidic fumes
*White + Green line = may contain cyanide fumes
*White + Yellow line = Chlorine gas
* Black = organic solvent fumes
* Green = Ammonia fumes
* Brown = Fumes from acid, organic solvents, and ammonia
*Purple = P100 - mold and asbestos
* Green + White Line = Acid and Ammonia fumes
* Blue = Carbon Monoxide
* Yellow = Acidic and Organic solvent fumes
* Yellow + Blue Line = Hydrocyanic acid gas and Chloropicrin vapor
*Magenta = Radioactive Material
*Red + Grey Line = Acid, organic solvent, ammonia, chlorine, and carbon monoxide
